Exhibit 99.1

Mylan and Upjohn, a Division of Pfizer, to Combine, Creating a New Champion for Global Health Uniquely Positioned to Fulfill the World’s Need for Medicine

HERTFORDSHIRE, England, PITTSBURGH and NEW YORK, July 29, 2019 – Mylan N.V. (Nasdaq: MYL) and Pfizer Inc. (NYSE: PFE) today announced a definitive agreement to combine Mylan with Upjohn, Pfizer’s off-patent branded and generic established medicines business, creating a new global pharmaceutical company. Under the terms of the agreement, which is structured as an all-stock, Reverse Morris Trust transaction, each Mylan share would be converted into one share of the new company. Pfizer shareholders would own 57% of the combined new company, and Mylan shareholders would own 43%. The Boards of Directors of both Mylan and Pfizer have unanimously approved the transaction.

The new company will transform and accelerate each businesses’ ability to serve patients’ needs and expand their capabilities across more than 165 markets by bringing together two highly complementary businesses. Mylan brings a diverse portfolio across many geographies and key therapeutic areas, such as central nervous system and anesthesia, infectious disease and cardiovascular, as well as a robust pipeline, high-quality

1

manufacturing and supply chain excellence. Upjohn brings trusted, iconic brands, such as Lipitor (atorvastatin calcium), Celebrex (celecoxib) and Viagra (sildenafil), and proven commercialization capabilities, including leadership positions in China and other emerging markets.

The transaction will allow the new company to meaningfully expand the geographic reach of Mylan’s existing broad product portfolio and future pipeline – including significant investments that have been made across complex generics and biosimilars – into new growth markets where Upjohn has existing sales infrastructure and local market expertise.

The combination will drive a sustainable, diverse and differentiated portfolio of prescription medicines, complex generics, over-the-counter products and biosimilars supported by commercial and regulatory expertise, established infrastructure, best-in-class R&D capabilities and high-quality manufacturing and supply chain excellence.

Financial Highlights

The new company is expected to have pro forma 2020 revenues¹ of $19 to $20 billion. Pro forma 2020 adjusted EBITDA is anticipated to be in the range of $7.5 to $8.0 billion, including phased synergies of approximately $1 billion annually to be realized by 2023. Pro forma free cash flow for 2020 is expected to be more than $4 billion.

The new company will be focused on returning capital to shareholders, while maintaining a solid investment grade credit rating. It expects to achieve a ratio of debt to adjusted EBITDA of 2.5x by the end of 2021. In addition, the new company intends to initiate a dividend of approximately 25% of free cash flow beginning the first full quarter after close and the potential for share repurchases once the debt to adjusted EBITDA target is sustained.

Leadership, Governance and Structure

The new company, which will be renamed and rebranded at close, will be led by Mylan’s current Chairman Robert J. Coury, who will serve as Executive Chairman of the new company; Michael Goettler, current Group President, Upjohn, who will serve as Chief

2

Executive Officer (CEO); and Rajiv Malik, current Mylan President, who will serve as President. Ken Parks, currently CFO of Mylan, has agreed to depart the company at closing. Heather Bresch, Mylan’s current CEO, will retire from Mylan upon the close of this transaction.

The Board of Directors of the new company will include its Executive Chairman and its CEO, as well as eight members designated by Mylan, and three members designated by Pfizer, for a total of thirteen members.

The new company will be domiciled in the U.S. and incorporated in Delaware and will operate Global Centers in Pittsburgh, Pennsylvania; Shanghai, China, and Hyderabad, India.

Executive Commentary

Robert J. Coury, Mylan Chairman, said, “Over the past year and a half, I have spent a lot of time speaking with and listening attentively to our shareholders. Today’s announcement builds upon many of those meaningful conversations and represents a transformative move for Mylan. The new company, which combines the unique assets of Mylan with the iconic brands of Pfizer’s Upjohn business, will not only accelerate our mission to serve the world’s changing health needs, but also further unlock the true value of our platform while delivering attractive returns to shareholders for many years to come. Importantly, the combined organization will have a presence across nearly every continent and major market, establishing a new leadership position in Asia, and offering products capable of treating all major therapeutic areas. This combination also further accelerates Mylan’s longstanding strategy to create the operational scale and commercial capabilities necessary to provide the world’s more than 7 billion people with access to medicine. As important, the transaction we are announcing today will enhance the strength of our balance sheet by scaling and increasing our existing strong cash flows, providing the new company with the financial flexibility to support and accelerate deleveraging and the expected initiation of a meaningful dividend from the first full quarter after the transaction closes. There will also be potential for share repurchases once the long-term leverage target is achieved. This powerful new profile positions the new company for sustained success and long-term value creation.”

Dr. Albert Bourla, Pfizer CEO, stated, “We are creating a new champion for global health—one poised to bring world-class medicines to patients across a wide range of therapeutic areas. I believe that Mylan’s unique profile and strategy has made it the obvious partner of choice in creating this powerful combination. By bringing Mylan’s growth assets to Upjohn’s growth markets, we will create a financially strong company with true global reach. I’m also excited about the management team, which combines strong executive talent from both companies, whose commitment to improving global health for patients and to delivering returns to shareholders are great assets for the new company. For Pfizer, this transaction represents our sharpened focus on innovative medicines and is a testament to our purpose – breakthroughs that change patients’ lives. At the same time, we’ll maintain the financial flexibility to advance our strong pipeline, invest for growth and continue to return capital to our shareholders.”

Coury continued, “The combination announced today also comes with Mylan CEO Heather Bresch’s decision to announce her intention to retire upon deal close after 27 years of distinguished service and leadership within Mylan. Heather has left a significant positive mark to the benefit of our company, patients and shareholders in so many ways including through her leadership and execution of our efforts to create a more sustainable Mylan. Her leadership helped to further position Mylan for this important milestone. Her presence and her impact will not only be missed by our Board of Directors, but also by our entire workforce of 35,000 across the world. We wish her much success with her future endeavors.”

Heather Bresch, Mylan CEO said, “Mylan was founded nearly 60 years ago with the core purpose to provide access to medicine. Thanks to the hard work and dedication of thousands of Mylan employees and the transformative vision from leaders past and present, including Board Chair Robert J. Coury, Mylan has made significant strides toward providing that same access at a global level for the world’s 7 billion people. And now, the creation of this new company introduces a powerful expanded platform with the potential for patient impact that will be truly transformative and unique within the industry. Nearly eight years after becoming CEO, I’m proud to say that this milestone represents the culmination of the goals I set for myself when I challenged Mylan and our amazing workforce to set new standards in healthcare. And so, as the company prepares to set out on this exciting new journey under the next era of leadership, I too have decided to pursue a new chapter – one that will continue to be focused on serving people, patients and public health.”

Coury continued, “Additionally, it is with great pleasure that I welcome Michael Goettler, a seasoned and high-quality pharma executive, as CEO of the new company. I am also pleased that Rajiv Malik will continue to serve in the role of president. Rajiv has been and continues to be instrumental in the building and execution of our true one-of-a-kind and very complex platform, and he will serve as a strong complementary partner to Michael. Lastly, I would like to thank Ken Parks for his leadership and service to Mylan, which has provided significant value to our company over the last three years, and know that he will continue to do so as we work toward a successful deal close.”

Michael Goettler, Group President, Upjohn added, “I’m honored by the opportunity to lead this new company, which will deliver more medicines to more patients across the globe. I’m also excited to combine two talented and deeply experienced teams that share a passion for providing patients with access to medicines. I look forward to delivering on that shared commitment by combining Mylan’s broad and diverse portfolio with Upjohn’s iconic, trusted brands and bringing the Mylan growth products to the Upjohn growth markets. I share Robert’s commitment to leading this new company with a focus on total shareholder return and look forward to working with leaders at the company towards that end.”

Mark Parrish, Chair of Mylan’s Strategic Review Committee, said, “This compelling combination concludes the work of Mylan’s Strategic Review Committee, which after our exhaustive review of available alternatives best positions the company to unlock value for our shareholders.”

Transaction Highlights

The combination will be effected through a Reverse Morris Trust, under which Upjohn is expected to be spun off or split off to Pfizer’s shareholders and simultaneously combined with Mylan. The transaction is expected to be tax free to Pfizer and Pfizer shareholders and taxable to Mylan shareholders. The transaction is anticipated to close in mid-2020, subject to approval by Mylan shareholders and customary closing conditions, including receipt of regulatory approvals. No vote is required by Pfizer shareholders.

Upjohn will issue $12 billion of debt at or prior to separation, with gross debt proceeds retained by Pfizer. Upon closing, the new company is expected to have a solid investment grade credit rating. The new company will have approximately $24.5 billion of total debt outstanding at closing.

Centerview Partners LLC and PJT Partners LP are serving as Mylan’s financial advisors, and Cravath, Swaine & Moore LLP and NautaDutilh are serving as legal counsel to Mylan. Goldman, Sachs & Co. LLC and Guggenheim Securities, LLC are serving as Pfizer’s financial advisors for the transaction. Wachtell, Lipton, Rosen & Katz, and De Brauw Blackstone Westbroek are acting as Pfizer’s legal counsel and Davis Polk and Wardwell LLP is serving as its special tax counsel.

Preliminary Financial Profile for Pfizer Upon the Completion of the Transaction

Pro forma for the separation of the Upjohn business, Pfizer expects to generate 2020 revenues of approximately $40 billion, driven by its science-based Biopharmaceuticals Group, with its Innovative Health business units (excluding Consumer Healthcare), including biosimilars, as well as a Hospital business unit that commercializes a global portfolio of patent-protected and off-patent injectable and anti-infective medicines.

In addition, Pfizer anticipates achieving Income Before Tax margins (expenses as a percentage of revenue plus other income and deductions) in the mid-30s% range and operating cash flow of $11 - $12 billion. Pfizer also expects that following the closing of the transaction the combined dividend dollar amount received by Pfizer shareholders in the event the equity distribution is structured as a spinoff, based upon the combination of continued Pfizer ownership and an expected 0.12 shares of the new company granted for each Pfizer share, will equate to Pfizer’s dividend amount in effect immediately prior to closing.

Exhibit 99.4

Statement from Mylan’s Board of Directors Regarding Retirement of CEO and Board Member Heather Bresch in Conjunction with the Combination of Mylan and Upjohn, A Division of Pfizer

HERTFORDSHIRE, England, and PITTSBURGH July 29, 2019—Mylan’s Board of Directors today shared the following statement regarding Heather Bresch’s retirement, which will be effective upon the closing of the combination of Mylan and Upjohn, a division of Pfizer. The transaction is anticipated to close in mid-2020, subject to customary closing conditions, including receipt of regulatory approvals, and approval by Mylan shareholders.

Mylan’s Board chairman Robert J. Coury said: “On behalf of Mylan’s board of directors, I extend my gratitude and respect for Heather Bresch’s years of extraordinary and passionate leadership at Mylan, which helped to pave the way for today’s historic announcement regarding the combination of Mylan and Upjohn. Heather began her career at Mylan in January of 1992 as a data entry clerk, and in January 2012, after 20 years and more than 15 different roles – including significant leadership positions as Chief Integration Officer, Chief Operating Officer and President – she was named the first female CEO of a Fortune 500 global pharmaceutical company. Upon becoming CEO, Heather established a blueprint for Mylan’s future that helped to bring about unprecedented growth for the company and create a truly diversified global organization.

During her almost three-decade tenure at Mylan, Heather has been instrumental in transforming the company from a 300 employee, $100 million revenue, single-country operation into a global organization that, upon close of the Mylan and Upjohn transaction, will have more than 45,000 employees, nearly $20 billion in revenue and a reach across more than 165 countries, including a new leading position in China. On behalf of Mylan’s Board, I extend tremendous thanks and credit to Heather Bresch for her many years of service to Mylan and for her authentic leadership style that helped to ensure Mylan’s mission of access could live on for years to come. In business and in public policy, Heather has challenged the status quo at every turn and is leaving this company, the communities in which we operate, and our industry in a better place.”

Mylan CEO and Board Director Heather Bresch said: “The opportunity to represent Mylan, and most especially our thousands of passionate and committed employees around the globe, has been one of the greatest joys and honors of my life. I am grateful to Mylan’s chairman, Robert J. Coury, and to our entire Board for their strong support throughout my career and for their leadership of Mylan’s differentiated strategy.

As I shared with the Mylan family today, upon my appointment to CEO in 2012, Mylan embarked on an initiative we called Healthcare 2020. It combined our efforts to blueprint the organization by enhancing global processes, infrastructure and diversification, with a future-focused strategy that ensured Mylan would explore opportunities to further differentiate itself for success in 2020 and beyond. Nearly eight years after becoming CEO, I’m proud to say that today’s announcement regarding the combination of Mylan and Upjohn represents the culmination of the goals I set for myself and our Company when I challenged our amazing workforce to set new standards in healthcare. So, as the company sets out on this exciting new journey, I too will be opening a new chapter that will continue to be focused on serving people, patients and public health.

I look forward to continuing to work with the entire Mylan family over these next several months to bring this transaction to a successful close, and to the exciting future for all of us.”

Exhibit 99.5

Our Mission Continues

July 29, 2019

To My Mylan Family,

Regardless of how long you’ve been with Mylan, you know our mission is a cause that is deeply personal. Providing access to high quality medicine has been our purpose since our very beginning. When I became CEO almost eight years ago, you willingly stepped up, eager to commit when I challenged us all to the audacious goal of providing the world’s 7 billion people access to medicine. Today, with the announcement to combine Upjohn, a division of Pfizer, with Mylan, our mission is truly within reach.

After much reflection and nearly 28 years of service, I believe that this historic milestone in Mylan’s amazing journey is also the right time for me to retire from Mylan and pursue a new chapter in my career, effective at the close of the transaction which is anticipated to occur in mid-2020. I know that for many of you, both announcements may come as a surprise, so I wanted to take a moment to explain why I think this transaction, and my transition, are the right next steps for Mylan.

As most of you know, I began my career at Mylan in January of 1992 as a data entry clerk; after 20 years and more than 15 different roles – including serving as Chief Integration Officer, Chief Operating Officer and President, I was appointed CEO. During my time at Mylan, I have been privileged to work with an incredibly talented and dedicated group of colleagues as we grew our company from a 300 employee, $100 million revenue, single-country operation to a global organization with over 45,000 employees, $20 billion in revenue and a reach of more than 165 countries, including China, as of the close of this transaction. My journey with Mylan has been life-altering, and the many relationships I have forged will be life-long.

From its very founding, Mylan’s story has been a uniquely special one. Created by two army buddies determined to succeed at providing patients in need with access to medicine, Mylan has never lost sight of its mission, or the indelible “fingerprint” that our founder and former CEO Mike Puskar left on Mylan and our culture that still serves the company well today. He established Mylan not only as a leading player in the U.S. generic pharmaceutical industry but also as an organization known for its commitment to quality.

His successor, Robert, significantly added to that legacy by transforming and expanding Mylan’s “footprint,” scaling the company virtually overnight from operating in a single country to reaching countries around the world as a result of two game-changing acquisitions in 2007. This global footprint resulted in a reimagined Mylan, essentially a 50-year-old company effectively becoming a global “startup” following these major transactions. These transactions also formed the extraordinary partnership of Robert, Rajiv and I that has not only endured the test of time but in many ways became the foundation of who Mylan is today. I am sincerely grateful to have had the opportunity to serve with them.

Robert’s visionary leadership not only transformed Mylan but also set a rare example in corporate America, where far too often, leaders stay too long. Robert’s resolve and his willingness to create the opportunity for me to become the first female CEO of a Fortune 500 pharmaceutical company was historic. I realize today more than ever the impact that decision had on my desire to create that same opportunity for the new company and its future.

Our leadership journey toward access hasn’t always been easy, but our efforts have had lasting impact. From treating approximately 40% of the world’s HIV+ patients to fighting for the same quality standards no matter where a product is made or helping to illuminate the complex supply chains that often make it difficult for patients and payers to get the full benefits of less costly medication, I am incredibly proud that Mylan has never shied away from challenging the status quo. These and many more demonstrations of our efforts to break down barriers to access have kept me continually energized over the years.

My focus throughout my time as CEO has been to build upon the “fingerprint” as well as the “footprint” that was established before me and create a “blueprint” for the organization to instill not only disciplined global processes, infrastructure and diversification but a future-focused “Healthcare 2020” strategy that allowed us to explore opportunities to further differentiate Mylan for success in 2020 and beyond. Looking back nearly eight years later, I am proud to say that with the creation of this new company, the goals I set for myself and for Mylan will be met.

So, as the company sets out on this exciting new journey, I too will be beginning a new chapter that will continue to be focused on serving people, patients and public health. I sincerely thank my management team and all of the employees of Mylan, past and present, for their partnership over the last three decades, and look forward to speaking directly with as many of you as possible over the coming months. In the meantime, in order to be in a position to fully realize the promise and countless opportunities our combination with Upjohn provides, it is important that we focus all of our collective energies on bringing this transformational transaction to a successful close.

As I have always believed, it is not the abilities of each individual player that leads to lasting success, but the strength of the entire team - the “Power of Us” truly can change the world!

With my deepest gratitude,

Heather Bresch

Mylan CEO
